Why Are My Clients Losing More Eyelash Extensions On One Eye?

As a lash artist, it is crucial to have a comprehensive understanding of the possible reasons behind uneven lash loss among your clients. This week, we're sharing the most common factors that can cause one eye to lose more lash extensions than the other.


First, consider differences in the environment, setup, cleansing method, and extension application technique between the eyes. Heat or humidity sources near one eye can affect retention, so adjust the lash room setup to avoid these differences.

When applying lash extensions, it's common to have the lash adhesive and palette on one side of the client's head. This can lead to one eye being further away from the adhesive, potentially causing issues with curing. If you use a fast drying adhesive, the lash extension may not form a proper bond by the time it reaches the further eye. To avoid this, you can try:

  • Tilting/turning the client's head to shorten the distance.
  • Picking up more adhesive when dipping the lash extension. 
  • Use a slightly slower-curing adhesive. Our Tempo adhesive is a good option with a 1-2 seconds dry time.

Poor application, especially on the harder-to-lash eye, can also cause retention issues, so use tape to assist in easier application and tilt the client's head for better visibility.


While less common than errors made by the lash artist, factors such as client aftercare, medical conditions and medications, and natural lash criteria can all play a role.

One common cause that's worth exploring is their sleeping habits. It's essential to ask your clients if they tend to sleep on one side more than the other, as this could result in more pressure on the lashes on that side, leading to uneven lash loss.

Another possibility to consider is allergies or irritation, which may cause clients to rub their eyes more frequently, resulting in lash damage and fallout.

Lastly, the natural shedding cycle of lashes could also be a contributing factor. To ensure that your clients have the best possible experience, it's vital to educate them on the potential causes of uneven lash loss and offer practical tips for preventing it. For instance, you could suggest using a silk pillowcase, which can help reduce friction and prevent lash damage while sleeping. 

Additionally, advising your clients to avoid rubbing their eyes can go a long way in preserving the integrity of their lashes. By providing knowledgeable and helpful guidance, you're not only helping your clients achieve their desired lash look, but you're also establishing trust and building a long-term relationship with them.
